Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Samsung SH100 and Panasonic GX1 side-by-side from the front, back and top in their relative dimensions. Samsung SH100 has external dimensions of 93 x 54 x 19 mm (3.66 x 2.13 x 0.75″) and weighs (including batteries). Panasonic GX1 has external dimensions of 116 x 68 x 39 mm (4.57 x 2.68 x 1.54″) and weighs 318 g (0.70 lb / 11.22 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung SH100 and the Panasonic GX1. Samsung SH100 is clearly the smaller of the two cameras. Its body is 23mm narrower, 14mm shorter and 20mm thinner than Panasonic GX1. As you can tell, actually this is not a fair size comparison since Samsung SH100 has a built-in lens but Panasonic GX1 doesn't. Once you put a lens on GX1, its thickness will increase significantly.
Here is the back view size comparison of the Samsung SH100 and Panasonic GX1.
Now lets look at the top view comparison of Samsung SH100 and Panasonic GX1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung SH100 is 318g lighter than the Panasonic GX1 but we don't think this will make a significant difference.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on GX1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Samsung SH100 nor Panasonic Lumix DMC-GX1 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Samsung SH100 and Panasonic GX1's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
